Measure epoch of timestamp-without-time-zone from local not UTC midni…
…ght. This patch reverts commit 191ef2b and thereby restores the pre-7.3 behavior of EXTRACT(EPOCH FROM timestamp-without-tz). Per discussion, the more recent behavior was misguided on a couple of grounds: it makes it hard to get a non-timezone-aware epoch value for a timestamp, and it makes this one case dependent on the value of the timezone GUC, which is incompatible with having timestamp_part() labeled as immutable. The other behavior is still available (in all releases) by explicitly casting the timestamp to timestamp with time zone before applying EXTRACT. This will need to be called out as an incompatible change in the 9.2 release notes. Although having mutable behavior in a function marked immutable is clearly a bug, we're not going to back-patch such a change.
